Specification of Letters Patent. i Patented M31-, 30, 192() Application le'd July 24, 1919. Serial No. 313,065.

To all 'whom t may concern:

Beit known that ,WILLIAM E. AVILLIN- onmacitizen of the United States of America, residingV at VilliaInsport, in the county of Lycoming and State of Penn.,rhave 1nvented certain new and useful improvements inAutomatic Stay-Arms, ofwhich the following is a specification.Y

The primary object of the present invention is the provision of a lid holding and releasing device, for phonographand other cabinets, Vthe same being automatic in its operation and not likely to become accidentally detached or released.

' manually.

A further object` of the invention is to provide'a support for the cover or lid of a talking machine cabinet, adaptedV for operation upon grasping and moving the lid without the necessity of engaging the hand of the operator,'with the invention.

With these general objects in view, my'invention consists of a device that is easy and inexpensive to manufacture,` and will be hereinafter fully described, in connection with the accompanying drawing.

In the drawing, forming a part of this application, and in which like reference characters designate corresponding .parts throughout the several views,

Figure 1 is a vertical longitudinal sec-V tional view-through a cabinet, 1n its open position, illustrating my invention installed thereon, Y l Y Y V-Fig. 2 1s a front. elevation thereof, with 'the Vcover removed, and

Fig. 3 is a perspective view of the safety mechanism employed for the stay arm, de-i l upon 'the downwarly curved upperside1 33 tached from-the cabinet.

Broadly considered, myinvention is serviceable in connection withcabinets such as lOhaving a cover .11, hinged to one upper edge'thereof, as 12, the invention being for the purpose of retaining the cover open, when desired, retained "against accidental closing but readily released, and closed A hanger 13 is'secured yin substantially the usual manner, interiorly of 'the cover 11, having the stay arm or bar 14C pivotally depending therefrom.

y The Cabinet 10 is provided with a motor board l5 with a slot 16 adjacent one side of the cabinet adapted for the receptionof i' a plate 17 through said slot, secured to the side of the cabinet as by screws or other suitable means. A guide plate'or liange 18 carried at right angles at one end of the r plate 17Yoverlies the slot 16 being secured byy screws'19 upon the board 15. A longitudinal slot 20 inthe plate 18 is adaptedk for the rece tion of the bar 141 therethrough, for

longitu inal movement during the opening and closing of the coverll.` i

An inverted V-shaped stop 21 is struck-up l from the-plate 11, while a hook-shaped supporting dog 22V is pivoted to the plate 17 by a post 23V in such a manner as to position one side or arm 24 of the stop'21, within the recess orl indented side 25 'of the hook 22. The dog 22 is capable of swinging relatively Aof the stop 21, a stud 26 upon thej plate 17,

' plane as the stop 21 by placing a washer 30 upon the post 23, between the plate 17 and 1 dog 22. An angularly projecting pin 31 ady jacent the free endofthe bar 14,1:is accommodated by a notch 32 at the outer side of the slot A20 during the intendedcomplete withdrawal of the bar 14, outwardl'ythrough `the slot 20 or the admission thereof, in-

wardly through said slot, when assembling the device. 1. Y

With the invention assembled,as shown in Figs. 1 and 2vof the drawing,- the ini tial entering of the lowerzend of the bar 14,

through the slot 20 with' the pinx31v passing through the notch v32, will bring saidpin 31 of the stop 21 permitting the bar 14 vto pass swinging ,the coverrto its open position, the barl 14C, is elevatedthrough the-'slot 20 until the pin 31 engages the throat ork socket 34: preventing further upward movement of the cover and bar, and upon permitting the bar to lower, the pin 31 will seat in the indented side 25 of the dog 22, for resting with the cover 11 held open, as best shown in Fig. 1 of the drawing. u f v When desiring to close the'covex` 11, the bar 14 is further elevated, by swinging the Ydownwardly for closing the coverll. Upon coverV 11 rearwardly upon its hinges 12,

bringing the pin 31 against Athe inner edge 35 of the dogportion 27 and swinging the dog away from the stop 21 until the pin 31 enters a recess in the upper end `of the closing of the cover 11.

Vmovingrearwardlyl of the dog 22, and the inclination of the bar 14 causes the weight f the cover 11 to automatically move the bar and its pin 31 downwardly during the The complete operation of theinvention will be apparent from this detailed description thereof, the repeated opening'and closin of the cover 11 taking place without any lia ilit of the pin 31 passing accidentally throug the slot 32, and while the dog support 22 supports the cover open, against accidental closing,V the' cover is readily opened and'closed at will, by the operator.A

While the form of the invention herein set forth is believed to be the preferable embodimentl thereof, it is nevertheless understood that changes may be made therein,

Y ywithout departing from the spirit and scope of my invention. The plate 17 with its flange 18 and stop 21, are' preferably formed integral of sheet metal, bent and struck-up in the positions described.

What I claim as new and desire to secure Vby YLetters Patent is LA cover support for cabinets, comprising in combination with the swinging barV carried by the lid of the cabinet, a pin upon the bar, a stationary stop adapted for initial engagement by' the pin, during both the closing and opening o the cover, anda swinging hook shaped dog adjacent the stop adapted for the seating reception of said pin Vwithin said dog, when the cover Vis opened.

2. In combination with a cabinet having a lid, a support bar pivotally depending from the cover, a plate carried byv the cabinet, having a fixed inverted V-shaped stop,

a hook-shaped dog pivoted on said plate, adjacent the stop, an the bar adapted for downwardly sliding Y stop.

a pin projecting from over the stop during the closing of the cover, and for engaging within the throat of the stop, when the cover is elevated, whereby the subsequent fall of the bar positions said pin supportingly within the indented side portion of the dog.

3. In combination with a cabinethaving va Vhinged cover, a swinging bar upon the cover, a perpendicularly mounted pin adjacent the free end of the bar, a plate carried by the cabinet, a stop upon the plate, adapted -for the engagement by the pin,

during the upward movement of the bar,

upon opening the cover, a supporting dog pivotedv to the plate, adapted for the seating reception of the pin, when the cover is opened, and for engagement by the pin during the upward movement ofthe cover, during the closing of the lid whereby the dog is swungrearwardly permitting the pin to move forwardly and downwardly, over said 4. A cover support for cabinets, comprising a bar pivotally attached to the cover of the cabinet, with a pin adjacent its free end, a stationary stop and a swinging dog upon the cabinet, the dog having an indented side, adapted for the seating reception of said pin when thecover isY opened, the stop having a curved side upon which saidv pin is adapted. to ride, during the lowering of the bar and the closing of the cover, the said dog having a recess adjacent its upper end substantially upon a level with the'top of the stop, adapted for guiding said pin onto said curved side of the stop. v Y f 5. In combination with a cabinet having a hinged lid, a swinging support bar carried by the lid, a plate inthe form of a slotted guide carried by the cabinet, having an entrance side notch for the slot, thereof, f

a projecting pin upon the bar adapted'to pass throughsaid notch during the entrance and exit of the bar, through the slot of said said pin, when the cover is opened, and a guide stop for the pin adj acently fixed relatively ofthe dog. f V In testimovry whereof I aHiX-m .si nature.
